본 연구의 목적은 선행연구에서 도출된 대학도서관 서비스 품질요소를 대상으로 재이용과 추천의향에 영향을 미치는 요인이 무엇인지 구조방정식 모형을 적용하여 분석하고자 하는 것이다. 2020.4.30.부터 2020.5.10.까지 11일간 이용자 그룹(학부생, 대학원생, 교수/강사) 총 127명을 대상으로 재이용과 추천의향에 대한 설문 조사를 실시하였다. 분석 결과는 다음과 같다. '자료'와 '서비스 고객화'는 재이용에 영향을 미치는 품질 차원으로 나타났으며, 재이용은 추천의향에 영향을 미치는 것으로 나타나 '자료'와 '서비스 고객화'가 재이용 뿐만 아니라 추천의향에도 영향을 미치는 것으로 분석되었다. 또한 '서비스 고객화'는 추천의향에 직접적으로 영향을 미치는 요인으로 나타났다. 이를 바탕으로 이용자의 요구가 다변화하고 개인화되고 있는 도서관 환경에서 도서관 서비스와 마케팅에 고객화 개념을 적용하는 방안을 제시하였다.

이 논문은 개인별 개인화 서비스 활용 로그를 추적조사 하여 개인별로 얼마나 많이 추천된 서비스를 사용하였는지 분석하고, 개인화가 적용된 시스템의 서비스 활용도에 영향을 주는 요인이 개인화 서비스 알고리즘외 다른 요인이 있는지 분석하였다. 또한, 분석 내용을 기반으로 단순히 많이 이용하는 서비스 및 콘텐츠를 추천하는 방법에 따른 사용자 이용패턴 분석을 통해 인센티브를 부여하였을 때의 행동변화에 따른 추천방법을 제안한다.

In this paper, the customized sports convergence contents curation system is proposed for activation of life sports. The proposed system collects and analyzes profile of social sports group (club, society, etc.) for recommending optimized sports convergence contents to user. In addition, the feedback based on the recommendation result from the user is continuously reflected and the optimal recommendation is made possible. For the system evaluation, the proposed system is tested to 300 users (about 20 sports team) for about 3 months and the system is verified by analyzing the initial recommendation results and recommendation results reflected by user feedback.

As consumers participate in sharing their experiences, they become a powerful information source in online shopping malls. Previous studies have investigated information service in the company-created information perspective and trust in the company perspective. This study extends the perspective of company-consumers to consumers-consumer perspective in information satisfaction and trust. Also, this study suggests loyalty as voluntary behaviors and adds helping behavior to the loyalty. Our results show that information satisfactions influence trust in the information sources such as company and consumers. Moreover, trust in company and trust in consumers influence loyalty differently. While trust in company influences recommending stronger than trust in consumers, trust in consumers influence helping and repurchasing stronger than trust in company.

The explosive growth of e-marketplace transactions requires an appropriate trust measuring framework to protect involving transacting entities such as buyers and sellers. As a strategic competitive edge, e-marketplace service providers have been adopting various system features that make sure no one transacting entity takes a major risk in online transactions involved. In this paper, an improved trust measuring method using fuzzy theory for an e-marketplace is proposed. The proposed methodology incorporates fuzzy set and calculation concepts to help build trust matrices and models, which are used to measure the level of risk involved in a specific e-marketplace transaction concerned. The proposed framework can be utilized to optimize the transaction costs by recommending a differentiated transaction process according to the risk level involved in each online transaction.

This study presented a personalization system that adopted a methodology which is applicable for digital content recommendation and executed by the Internet service providers. The system made a recommendation to the users on the basis of their preferences, while most techniques for recommending digital content have focused on considering the similarity of content. In addition, it developed a method of evaluation to determine the priority of recommendations and adopted measures when selecting a set of recommendations. To experiment the feasibility and effectiveness of the presented methodology, a prototype system was developed and was applied to an English newspaper on the Internet.

온라인 상에서 불특정 타인과 관계를 맺을 수 있는 서비스로 소셜 네트워크 서비스(Social Network Service : SNS)가 새롭게 떠오르고 있다. 1990년대에 등장한 SNS는 최근에는 스마트폰을 이용한 모바일 서비스로 인해 이용자의 수가 급격히 늘어나고 있다. SNS에서는 '친구 찾기' 라는 서비스를 제공하는데, 이는 이용자의 개인정보를 분석하여 이용하여 친구를 찾아주는 서비스이다. 기존의 '친구 찾기' 서비스는 이용자가 제공하는 정보만을 다른 이용자의 정보와 비교하여 친구를 찾았다. 그러나 이용자가 제공하는 정보는 한정적이기 때문에 비교할 수 있는 정보의 양도 한정되어 찾을 수 있는 친구의 수에도 한계가 생긴다. 그래서 본 논문에서는 단순한 개인정보 비교를 통한 친구를 찾는 방법이 아닌 이용자가 제공하는 시공간 데이터를 활용하여 추론을 통해 친구를 추천해주는 시스템을 설계하고 구현한다.

ChatGPT has had a significant impact on society, business, and academia by influencing individuals and organizations through knowledge generation and supporting users in locating conversational inquiries and answers. It can transform how people seek answers by combining human-like conversational skills with AI. By eradicating the cumbersome process of selecting from multiple options, users can conduct preliminary research or create optimized solutions. The purpose of this research is to investigate how consumers use ChatGPT and digital transformation, specifically in terms of knowledge development, searching and recommending, and optimizing accessible possibilities. Using many linked theories, we address the potential implications and insights that can be gained from ChatGPT's early stages and its integration with other applications such as robotics, service automation, and the metaverse. Finally, the application of ChatGPT has practical, theoretical, and phenomenological impacts, in addition to improving users' experiences.

Purpose - A product bundling is a marketing approach where multiple products or components are packaged together into one bundle solution. This paper aims to introduce an optimal bundle search problem (hereinafter called "OBSP") which may be embedded with online recommendation system to provide an optimized service considering pairwise discount and delivery cost. Research design, data, and methodology - Online retailers have their own discount policy and it is time consuming for online shoppers to find an optimal bundle. Unlike an online system recommending one item for each search, the OBSP considers multiple items for each search. We propose a mathematical formulation with numerical example for the OBSP and analyzed the complexity of the problem. Results - We provide two results from the complexity analysis. In general case, the OBSP belongs to strongly NP-Hard which means the difficulty of the problem while the special case of OBSP can be solved within polynomial time by transforming the OBSP into the minimum weighted perfect matching problem. Conclusions - In this paper, we propose the OBSP to provide a customized service considering bundling price and delivery cost. The results of research will be embedded with an online recommendation system to help customers for easy and smart online shopping.

As the South Korean government has recently announced its intention to implement a three-year policy on building additional libraries and complex community centers as the community-based everyday life SOC project, society has shed new light on libraries as public service institutions. Accordingly, this study was conducted to determine the factors affecting resident satisfaction with public libraries, intention to use, and intention to recommend public libraries, for use as basic data to increase resident satisfaction and use of public libraries in South Korea. To this end, we conducted a survey on residents who have experience with using 13 public libraries designated as regional representative libraries in South Korea. The surveyed data was verified with a structural equation using AMOS. The results were as follows. First, all factors, such as material, facility, staff, program, and service, except location and space, had a significant effect on resident satisfaction with public libraries. Second, it was found that satisfaction had a significant effect on the intention to use and intention to recommend. The results of this study may contribute to qualitatively improving public library services by reflecting the changing needs of users, as well as social trends at the working level of libraries in South Korean society.
